Google just made this announcement today:
The Nik Collection by Google: photography first, for professionals and more
Here on the Google+ Photos team, we're busy building tools for all kinds of photographers. Today, and for all the professionals out there, we're bundling the complete set of Nik plug-ins as the Nik Collection by Google. We're especially excited about three things:
1) It's more affordable. The entire set of plug-ins for Photoshop, Lightroom and Aperture only costs $149 (versus the previous $499).
2) It's really powerful. The Nik Collection by Google gives you tools for everything from noise reduction and HDR imaging to creative effects and image sharpening (and lots more).
3) It's free to try. You can visit niksoftware.com for a 15-day free trial of the Collection.
If you've already purchased one or more Nik plug-ins in the past, then don't worry, we've got you covered. In fact: we're going to upgrade you to the entire Nik Collection by Google for free. Just keep an eye out for emailed instructions in the next few days.
I just got my email and I am going to upgrade now.
